Driver technology

Like all models of the AX series, the A77X features the ADAM proprietary X-ART tweeter. The ʽXʼ stands for ʽeXtended frequency responseʼ and thus for one of the features of the Accelerating Ribbon Technology that has been drastically improved: the frequency response. It now extends all the way up to 50kHz. In addition, the X-ART tweeter has higher efficiency and higher maximum sound pressure levels.

The two 7” woofers are identical with that of the A7X. With their large voice coils (1.5”) and powerful amplifiers, they are capable of both very high maximum sound pressure levels as well as very deep registers. The woofers do not cover the same frequency bands: while both of them are responsible for the (sub-) bass frequencies up to about 400Hz, only one of them reproduces the midrange. This prevents interferences between the two drivers. For stereo setups the A77X is available in A and B versions in order to guarantee a precise stereo image.

Amplifiers / controls

Each driver has its own dedicated amplifier. A 50W A/B amp is responsible for the X-ART tweeter, while the bass-/midwoofers are driven by a 100W PWM amp each. The front panel includes a power switch and a control for the volume that retains the volume setting independently from the on/off switch.

The rear panel features several additional controls: a gain for the high frequencies (± 4dB) and two shelf filters for high and low frequencies.
To ensure greater compatibility, there are both XLR (balanced) and RCA (unbalanced) connectors.

Review samples:

“… a refreshing change“
"… if you liked the A7X youʼll like the A77X even more, and if the companyʼs smaller near-fields werenʼt your cup of tea, the A77X are definitely worth another listen. They are not much bigger than a two-driver cabinet design, so should slip into any installation where a near-field speaker will fit, but the extra low/ mid frequency drivers mean that the bass is more naturally extended and the mid-range clearer and more detailed. I like the A77X a lot and they make a refreshing change from the usual mid-priced near-field speakers." AUDIO MEDIA magazine / February 2012

“… wide and spacious soundstage with solid left/right imaging“
"… they are fun and easy to work with, covering all the essential functions required of high-end monitors with aplomb." MusicTech magazine / April 2012

PRICE PER UNIT

S1X

The S1X nearfield monitor delivers high quality sound in a very small cabinet. The S1X has all the critical features of the new SX-Series: the X-ART tweeter in combination with the ADAM designed class A/B amplifier and the HexaCone woofer with optimized magnet/voice-coil systems, driven by premium PWM amplifiers.

The smallest reference speaker

The combined features of crystal clear resolution, tight and precise low-frequency reproduction and the effortless musical reproduction sets this speaker apart from all conventional designs.

The S1X is the first choice in all environments that require high quality within a small space, whether it is a smaller studio, an OB vehicle, or a 5.1 installation.
